well the main difference is that a horses spine is made of bone while a sharks is made of cartilage.
Sharks indeed have a backbone. End of story.
they have a backbone
They just know......
Sharks Dont have a "backbone" persay, but they do have a special interior bone like thing. (thats the best way i could put that) The bone like thing consists of catrilidge. which acts somewhat as a "Backbone".
sharks have large crap we have crap 75% smaller
Sharks are cold-blooded, and are a species of fish; Dolphins are warm-blooded, and are mammals.
Well,there has to be a difference between them or people would not have named them differently.
No. an invertebrate is an animal without a backbone.
they don't come from the same family like bull sharks they are not part of the hammer-head shark
Some sharks have bones like us however some sharks have bones that are made out of cartilage.
One difference is that fish are bony. Sharks have a skeleton made of cartilage (like in your nose or kneecap). Sharks have five to seven gill slits, while fish only have one. Fish have swim bladders for bouyancy, sharks do not.
